' RAILWAY TIE.

This invention relates to improvements in concrete railway ties.

The principal object of my invention is to provide a tie comprising a pair of spaced blocks of plastic composition, with means for maintaining the blocks in their spaced relation, together with simple andpractical devices for securing the rails tothe ties.

A further object of the invention is to provide a tie formed of two blocks, one positioned beneath each rail, between which extends suitable securing means to hold the blocks in their spaced position, the blocks being tapered from their middle portion toward their opposite ends to more securely anchor them against endwise displacementand to facilitate tamping about them of the road bed ma: terial.

A still further object of the invention is the provision of a concrete block forming a supporting sleeper for a railway track having a middle portion of square configuration and having a plane under surface upon which the.

block rests in use and tapered from its middle portion toward its ends on all sides except one,

together with means for rigidly mounting a railway track on either side of said tie including. apertures extending vertically through the block counter-sunk on the under side through which rail securing bolts are extended having their heads received in said countersunk portions beneath the block. F

A still further object of theinvention is to provide a tie comprising spaced rail supporting concrete sleepers; which may be reversed to use either side up for supporting the rail and upon which rails-ofall standard sizes may be secured without changing the sleeper blocks.

Other objects and advantages of my in: vention, and objects relating to details of construction and arrangement of parts thereof, will be readily apparent in the course of the detailed description to follow.

I And a still further object of my invention caused by train movement over the rails. II

have found that coinminuted compounds, as

increase the bearing value of the tie when placed within the tieduring the'moulding of the same within the aggregate.

And still further objects of my new and improved tie consist in the forming of the tie in a manner that permits of the placing of the same either side up depending upon the character of the supporting soil upon which the same is to be placed and the curva- I ture of the roadbed and the speed at which the trains are to be operated. thereover. Reinforcing is placed within the' tie to increase the supporting value of the same and to pre vent distintegration dueto overstressing as occurs when the same is not reinforced.

WVith these and incidental objects in view, the invention consists in certain novel features of construction and combination of parts, the essential elements-of which are set forth in the appended claims, and a pre ferred form of embodiment of which is hereinafter shown with reference to the drawings which accompany'and form a part of this specification.

. Fig. 10 is a cross section view, taken on line 10-10 of Fig. 7 looking in the direction indicated.

Like reference characters refer to like parts throughout the several views.

Referring to said views, the reference numeral 1 indicates each of a pair of blocks comprising a railway tie which is formed of concrete or other suitable plastic composition. Said blocks are each formed with a bottom face2extending its entire length. The side faces of the block are rectangular to said bottom face and are parallel to each other in the middle portions 3 while they are tapered toward their ends from said middle portions, as at 5. The upper surface of the block extends in a plane parallel to the lower surface 2 in its middle portion 6 corresponding to the middle portion 3 of the sides and therefrom is sloped, as at 7, toward the inner and outer ends of the blocks 8 and 10, respectively.

Each of the blocks is formed substantially at its major axis with a hole 11 extending throughout its length. A metal tie rod 12 is adapted to extend through the holes 11 to tie the blocks together in their spaced relation. A head 13 is formed on one extremity of the rod engageable with the outer end 10 of a block while the opposite end of the rod is formed with screw threads 15 with which a nut 16 is engaged to bear upon the outer end 10 of the oppositely disposed block and through which the distance bet-ween the blocks may be adjusted to provide for the various gauges of track. v

Collars 17 are placed upon the rod 12 and brought to engage the inner ends 8 of the blocks, where they are secured by set screws 18, thus tying the rods and blocks together in a unit. Washers 20 are interposed between the collars and the block and also between the head 13 of the rod and nut 16, in the customary manner.

The blocks are further formed with apertures 21 extending vertically therethrough in symmetrically spaced relation upon'each side of the transverse axis and between which the track rails 22 extend. Said apertures are provided with recesses 23 at eaclrend within which on the under side of the block the heads 25 of bolts 26 are entered which project therefrom to an extent sufficient to enable the track repairer to engagethem by a suitable wrench.

' Said bolts extend upwardly through the apertures 21 and pass through clips 27 spanning the recesses 23. The clips are extended over the lower flanges of the track rails 28 and are secured by nuts 29 on the bolts 26. The clips 27 are each formed with a shoulder 30 engaging the outer edge of the track flange so that upon changing the size of the rails the sleeper blocks need not be changed but only different clips employed having their shoulders formed to suitably engage the rail edge.

The configuration of my improved tie plane blocks is of great advantage in the utility and success of my improved tie. The block being tapered in both directions from its middle portion may be seated more securely in the road bed and with less danger of being displaced longitudinally as it may be tamped tighter and tends to increase the resistance against the road bed material in moving in either longitudinal direction.

It will be seen that my improved concrete rail sleeper blocks are reversible, each affording two faces for supporting the rail, one side providing a flat surface and the other having a flat middle portion and surfaces inclined slightly therefrom toward the ends. Either of these opposite sides may be present-ed up permost at the option of the track layer, using his best judgment as to the advantages .under the varying condition of road bed and usage. Either side may thus be. used, andupon the wearing or damaging of the rail supporting surface the sleeper block may be reversed to present a new surface and thus increase the life and utility of the tie. 1

Under certain conditions it is highly desirable to reinforce the tie elements during, the forming of the same from plastic materials and since the ties are to be reversible fordifferent conditions and to increase the lifeof the same, the reinforcing elementsare preferably made uniform and of a single piece.

One or more sets of the reinforcing elements entering the construction of the tie as formed. In the preferred embodiment the reinforcing is as illustrated in Fig. 7 at 31 with a cold shut 32 disposed at the meeting ends. A reinforcement made as illustrated may be placed within the tie with a minimum of time and labor, and be made to give uniformly satisfactory results. v

r In train operation, and especially in main line construction where heavy. loads are moved at relatively high speeds there is a substantial movement of the rail relativeto the tie. The constant movement of the rail upon the tie causes a frictional erosion of the tie element. To overcome this erosion I have found that the life of the tie may be greatly increased by the placing of a quantity of comminuted.

metallic elements in the aggregate at the point of contact of the rail with the tie. This is shown at 33. 1 r 7 "From the foregoing description, taken in connection with the accompanying drawings, the advantages of the construction and application of my improved railway ties will be readily apparent; but, while I have described the principle of operation of the invention, together with the devices I now consider the best embodiment thereof, it will be readily apparent that the structures shown are merely illustrative and that changes may be made therein.

While the form of mechanism herein shown and described'is admirably adapted'to ful fill the objects primarily stated, it is to be understood that it is not intended to confine the invention to the one form of embodiment herein shown and described, as it is susceptiv ble of embodiment in various forms, all coming within the scope of the claims which follow.

What I claim is p 1. In a device of the class described, the combination of a tie element made of concrete aggregate in its main body portion, having rail supporting surfaces arranged at oppositely disposed sides, and comminuted metallic elements formed within the aggregates at such rail supporting surfaces.

2. In a device of the class described, the combination of a tie element made of plastic aggregate, said aggregate having reinforcement placed therein for increasing the supporting value of the tie element, rail supporting surfaces disposed upon opposite sides of the tie elements and means disposed within the aggregate at the point of rail contact for increasing the wear resisting value of the tie and the supporting value of the same at such surfaces.

3. In a device of the class described, the combination of reinforced concrete tie elements having rail supporting surfaces disposed on one or more sides thereof and finely divided metallic elements placed within H the aggregate while in a green condition at a such rail supporting surfaces. 4. In a device of the class described, the combination of reversible railway 'tie elements formed of concrete aggregate, pairs of rail holding down bolts disposed at either side of the rail supporting surfaces disposed upon the tie surfaces and means for increasing the supporting value and wear resisting value of the rail surfaces by the placing of comminuted metallic elements within the aggregate at the contact of the rail with the tie.

5. A railway tie having one or more rail surfaces formed thereupon and finely divided metallic compounds formed withinv the tie where the rail engages the same.

6. A reinforced concrete tie having one or more rail supporting surfaces formed upon the tie and finely divided metallic elements disposed in such surfaces.

rality of rail engaging surfaces formed upon mally possessed by the concrete alone.
